' Application filed April 27, 19Go. Serial No. 31.15056.

To all whom it 'may concer/1i."

Be it known that I,4 FREDERICK SNOW, e citizen of the UnitedStates, residingin the city of Chicago, in the county of Cool: and State of illinois, have invented e certa-in new, useful, and improved Driving and llei-'eising lllechiinism, of' which the following a specifica-tion. v

My invention relates to driving and reversing imechsnisms, and has particular- .reference to. nmecha-nism intended for and zylinder is driven first in one direction and' l then inthe other, to thoroughly agitato the garinentsfand subject them to the Washing action of the fluid.' To 4olotnin the best re# sults,-the cylinder revolutions must be equal iu the two directions;otherwise, the germents will he' rolled or ,balledinto masses and vrill not receive the full benefit of the washing` operations. V

The mechanisms'now used upon Washing machines are objectionable because they nre inexact in voperation,which results in cziusing unequal,nlternutions ofthe cylinder, with attendant loss of'etliciency.

'lhe object of my invention isto provide a driving and reversing mechanism, for washing-inachines and the like, which shell automatically limit the rotation of the cylin; der lo an exact peripheral t 'aveh equal in lioth directions,` l conceive, furtlnfr, that, to a great extent, the usefulness of n Wushingnnachine depends upon the suddenness `with which the cylinder reversals are accomplished; that the pressure and driving force of -thel waslungdiuid is inversely propon- -tio'nal to the time occupied lin changingthe rotative direction of the cylinder; andthnt,l as this-reversal moment is shorlened,'the pressure and loirof the .fluid through the garments conlincd inl the. cylinder will be increased, und the `time required `for their cleansing decreased. l i -further find particular object of my invention is, therefore, to provide 'drivingj Specification of Letters atent.

Patented Feb. 9, 1909.

and reversing mechanism hy which quick or sudden reversals of the Washer-cylinder may be accomplished, with a view to increasing the practical eiliciencyof such machines.. y

Still another object 'of the invention ifs to provide an alternative driving mechanism which he ndjusted to automatically reverse the Washencylinder et the end of each .v

first, second, third or fourth revolution, or fractions thereof, to adapt the nvnsher to different classes of Work, and thnsfto provide for 'e saving of time when only short revolutions arel required.

A further object of the invention iste provide a driving' and reversing mechanism that shall4 he operatively self-contained in other words, one Whose operations and reversals shell. in no Wise oe dependent upon `the Washer-cyliiider or other driven element or member, so far as concerns the forces necessary to accomplish such reversals.

` With these objects in view, my invention consists, generally, vin :i driving and reversing' mechanism 'comprising o. reversrhledriyingr-shaf'hin combination with Athe member .to Yhe drivenend rever; ed, means for driving said shaft in either direction, :ind e dei. vice. driven from such shaft and controlling the operationof said? ineens, wherebyv the peripheral elternetions or rotary reciprocations of the sl fiere accomplished; and

my` invention consists, further, ,in various details of construction and in combinations of parts, all ns hereinafter described and particularly pointed ont in the claims.

The hubs of 12s and'll* are secured tothe 'shaft bv keys (52, 0". and the rotation ofthe :Shafh-; will depend upon. which .of the two clutch members 125.13 ieconnectcd with ite complementary clutch part.

ring to- Figs. 10,19, Q0 and 2l., it' will -be seen that the band, 16, has its end 1li attached to ofthe clutch.. lt el'lcirjclesY the inner, continuously driven, part of the clutch. The opposite end of the band is pro? rided with an angle piece or block, 16g-en# raged by the clutch tightening arm 16j?. The arm 16S le pivoted on said clutch r'nei'noersl 12S, or 13S, and the lfree .or arm endl of this lcver'extends to a position' at the Side ofthe'l -huh of said part 1:2S 13S,-for;engage1nent by and with the sliding cone or collan'of the 1llV'hcn the innerer free end of the clutch arm is forced outwardly the short I:zriu of the lever .is movd'to-force the ends of t hebandmoile nearly together and tighten .said band'upon theinner end ofthe clutch.

This beingv done the outer clutch partwill .rotate with tliefinner clutch part, and the fshaft; for thetime being, willloe posi'- tively onnected to 'said inner part. A set screw inthe clutch-arm 153 `provides means for taking up wearlietween'the' parts. It

Awill he ohvious that byconnecting; first one 'clutch' and thentlie othcrto the shaft, G, 'said 'Shaft und the' washer cylinder geared thereto.' will 'he caused to rotate irst in 'one ldirection andthcn the other.v

'The s/l'fcz--rlllie ehifte." for'operating lie-clutches includes 'the shaft, T, the arme," 'y1 at the ends of the shaft, and the cones or collars and 73, before mentioncthon the hubs or slecvce of the clutch parte 12S and 13?. The concs may or may not rotate with Uiv Said clutch parte, but are always Slidable upon said hubs. When the shaft or rod, 7, v.moved longitudinally one cone will loe moved out of engagement]with its clutch arm while the other will he moved into engagement with tlu\,"arn'1 of the opposite '.clutcli.. rllhe shaft, 7, is arranged to slide i'nv the 'hearings on tho lu'acltct, and isprovi'ded iith an arm, 7*, having a pin. 7'?, that engages thc cam groove S" of the Shifter motor. vThe rotation ofthe motor cam, 8, will rauee longitudinal movement of shaft, 7, and

the two concs. 72 and 7:i ,that are connected Awith it: Thus each partial revolutionof `the cam or motor, S, operates to change the clutches upon the drivingr Shaft G.

ing and driving saidcam at intervals. It would ,not be practicable to employ a cam that rotated continuously, inasmuch as the movement'of the clutches vmust occur within a fraction of the time during' which the driving shaft ie in rotation in' either of its directions. Hence, my employment of a shifter motor that is normally Stationary and which operates. at intervals only.

5s ie a part of the bracket, 5, which carries alarge stud-shaft, 17 on which the motor cam, 8, is journaled. The stud Shaft also,

carries a tripping collar, 18, and a gear wheel, 19. The gear, 19, meshes with the pinion 122 and is.- driven continuously. Re-

ferrin'g to Figrill,l it Will be seen that the tween the collars, 17 and an end collar, not Sh own.

The inner side 19 of the. gear wheel19 isturned smooth, and 2O represente a brake shoe that ie attached to the cam, 8, and which is pressed against-the gear wheel7 ttl, by a'spring, 20. The purpose of thelnalte shoe Will be pointed out heraifter.

192 is a clutch part on the gear, 1t), adapt.

ed to he engaged by a clutch slide S on the part When the parts 82 and 192 are in engagement, as slunvn in Figs. 11 and 12, the cam, 8, will be 'rotated with the gear wheel, V19. As the shifter is connected with the cam, S, by the medium ofthe pin, T5, and the cam groove, it will he obvious` that the rotation of the cam will at this time operato ,to tluo\\"the shifter rod and change the clutches upon the main Shaft. This being truc, it 1s only necessary to provide means for intermittently operating' theclntch slide,

8'2". to lreliably 'regulate the operation of the shifter and the parts-d-epemle1it upon its action.
